6. Blasting <br />Blasting has taken place underground since the turn of the century and has not resulted in any damage to <br />any structure in the nearby area. Minor blasting of marble blocks on the surface may be used to <br />construct the sediment control system, in particular, the construction of Sump 4 and the ditch leading to <br />it. These blasts are very small and will not result in any damage to nearby structures. All blasts will be <br />performed according to MSHA procedures and will be designed to keep nearby structures intact. <br />The structures identified for the underground blasting are: <br />Private Trail: 195 feet at the closest point. <br />Old cable tower: 15 feet at the closest point. <br />Macintyre house: 1000 feet at the closest point. <br />Macintyre cable tower: 570 feet at the closest point. <br />The surface blasting for Sump 4 is the closest point of this type of blasting to the nearby structures: <br />Private Trail: 50 feet at the closest point. <br />Old cable tower: 415 feet at the closest point. <br />Macintyre house: 930 feet at the closest point. <br />Macintyre cable tower: 430 feet at the closest point. <br />7. Storage Area <br />The Storage Area in Marble, CO is used to store the marble blocks prior to shipment to customers. See <br />Map C-3 for the layout of this area. The area is flat and has not had any problem with erosion, stability, <br />etc. There are no fuels or other structures stored on this site. The 2010 Amendment will cover a larger <br />area than in the past, but this area is expressly for additional storage of cut marble blocks. See picture <br />below of the Storage yard area. <br />Yule Quarry April 10 34
